This component meters refrigerant flow through the refrigerant circuit, controlling the pressure drop between the high side and low side of the system. Proper orifice sizing is critical to maintaining correct subcooling, superheat, and system efficiency. Licensed HVAC technicians install this part during routine service, refrigerant circuit repair, or when replacing a damaged or incorrect orifice in the system.\u003c\/p\u003e\n\u003cp\u003eThis restrictor orifice is used in the PPA1SC060K 12 SEER single packaged air conditioner under the PPA1SC model family. Packaged units are self-contained systems typically installed at ground level or on rooftops in residential and light commercial applications. The orifice is located in the liquid line circuit and is accessed during refrigerant system service. This part is specific to the PPA1SC series and is not a universal metering device.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFixed orifice design meters refrigerant flow in the 12 SEER refrigerant circuit\u003c\/li\u003e\n  \u003cli\u003eOEM-specified replacement for the PPA1SC060K packaged unit\u003c\/li\u003e\n  \u003cli\u003eMaintains correct system refrigerant pressure differential for rated efficiency\u003c\/li\u003e\n  \u003cli\u003eCompact form factor fits within the existing liquid line assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the WESTINGHOUSE PPA1SC060K 12 SEER Single Packaged Air Conditioner, PPA1SC model series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a certified HVAC technician holding an EPA Section 608 refrigerant handling certification. Recover all system refrigerant before opening the refrigerant circuit to access or replace the orifice. Verify the replacement orifice designation matches the original before installation to avoid capacity or efficiency loss. Recharge the system to manufacturer specifications after completing the repair and leak-check all opened connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Type\u003c\/strong\u003e: Restrictor Orifice\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: 12 SEER Single Packaged Air Conditioner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Model Number\u003c\/strong\u003e: PPA1SC060K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Model Series\u003c\/strong\u003e: PPA1SC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WESTINGHOUSE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 664103\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284145439026,"sku":"664103","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277975.png?v=1781069713","url":"https:\/\/voomisupply.com\/products\/westinghouse-664103-restrictor-orifice-12-seer-packaged-ac","provider":"Voomi Supply","version":"1.0","type":"link"}
